java中如何根据一个网址获得该网页的源代码？

package test;

import java.io.BufferedReader;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.URL;

public class HttpTest {

private String u;

private String encoding;

public static void main(String[] args) throws Exception {

HttpTest client = new HttpTest("", "UTF-8");

client.run();

}

public HttpTest(String u, String encoding) {

this.u = u;

this.encoding = encoding;

}

public void run() throws Exception {

URL url = new URL(u);// 根据链接（字符串格式），生成一个URL对象

HttpURLConnection urlConnection = (HttpURLConnection) url

.openConnection();// 打开URL

BufferedReader reader = new BufferedReader(new InputStreamReader(

urlConnection.getInputStream(), encoding));// 得到输入流，即获得了网页的内容

String line; // 读取输入流的数据，并显示

while ((line = reader.readLine()) != null) {

System.out.println(line);

}

根据具体问题类型，进行步骤拆解／原因原理分析／内容拓展等。

具体步骤如下：／导致这种情况的原因主要是……

Java网站的源代码怎么在本地运行

首先 java网站是基于jdk运行的。你得先装jdk。去官网下载一个jdk安装。然后你得编译你的项目，打包到容器（tomcat,weblogic,jboss等）中运行即可。再提醒一下就是，看看你的源代码有木有用到数据库或者其他类型的服务。如果有的话，你得装数据库或服务，并且初始化数据。再启动你的你的容器。

运行时可调用浏览器打开一个网页，网页地址在代码中的java代码怎么写？

网页地址在代码中的java代码写法如下：

package com.test;

import java.lang.reflect.Method;

//实现打开浏览器并跳到指定网址的类

public class BareBonesBrowserLaunch {

public static void openURL(String url) {

try {

browse(url);

} catch (Exception e) {

}

private static void browse(String url) throws Exception {

//获取操作系统的名字

String osName = System.getProperty("os.name", "");

if (osName.startsWith("Mac OS")) {

//苹果的打开方式

Class fileMgr = Class.forName("com.apple.eio.FileManager");

Method openURL = fileMgr.getDeclaredMethod("openURL", new Class[] { String.class });

openURL.invoke(null, new Object[] { url });

} else if (osName.startsWith("Windows")) {

//windows的打开方式。

Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);

} else {

// Unix or Linux的打开方式

String[] browsers = { "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" };

String browser = null;

for (int count = 0; count browsers.length browser == null; count++)

//执行代码，在brower有值后跳出，

//这里是如果进程创建成功了，==0是表示正常结束。

if (Runtime.getRuntime().exec(new String[] { "which", browsers[count] }).waitFor() == 0)

browser = browsers[count];

if (browser == null)

throw new Exception("Could not find web browser");

else

//这个值在上面已经成功的得到了一个进程。

Runtime.getRuntime().exec(new String[] { browser, url });

}

//主方法测试类

public static void main(String[] args) {

String url = "";

BareBonesBrowserLaunch.openURL(url);

}
